摘要： A nickel-based active material precursor includes a particulate structure including a core portion, an intermediate layer portion on the core portion, and a shell portion on the intermediate layer portion, wherein the intermediate layer portion and the shell portion include primary particles radially arranged on the core portion, and each of the core portion and the intermediate layer portion includes a cation or anion different from that of the shell portion. The cation includes at least one selected from boron (B), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), titanium (Ti), vanadium (V), tungsten (W), chromium (Cr), iron (Fe), copper (Cu), zirconium (Zr), and aluminium (Al), and the anion includes at least one selected from phosphate (PO 4 ), BO 2 , B 4 O 7 , B 3 O 5 , and F.

摘要： The present invention relates to NICKEL-BASED ACTIVE MATERIAL PRECURSOR, METHOD OF PREPARING THE SAME, NICKEL-BASED ACTIVE MATERIAL, AND LITHIUM SECONDARY BATTERY. A nickel-based active material precursor for a lithium secondary battery includes: a secondary particle including a plurality of particulate structures, wherein each particulate structure includes a porous core portion and a shell portion, the shell portion including primary particles radially arranged on the porous core portion; and the secondary particle has a plurality of radial centers. When the nickel-based active material precursor is used, a nickel-based positive active material having a short lithium ion diffusion distance, in which intercalation and deintercalation of lithium are facilitated, may be obtained. A lithium secondary battery manufactured using the nickel-based active material may exhibit enhanced lithium availability, and may exhibit enhanced capacity and lifespan due to suppression of crack formation in the active material during charging and discharging.
